- Unlike other violent crimes, the daily timing of robberies committed by youth peaks at 3 p.m. and 8 p.m. on school days and at 10 p.m. on nonschool days.
- Before 8 p.m., persons are more at risk becoming an aggravated assault victim of a youth on school days than on nonschool days (i.e., weekends and all summer days).
- Sexual assaults committed by youth spike at 8 a.m. and noon on both school and nonschool days and at 3 p.m. on school days.
